Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the number of the light board layers 20 is greater than one, in addition to the first pressure strips 31 arranged on the uppermost and lowermost sides of the display module, the plurality of first pressure strips 31 are also arranged. The second pressure strip 32 between two adjacent light board layers 20, the second pressure strip 32 and the first pressure strip 31 together fix the plurality of light board layers 20 on the back plate 10; the light board layer 20 includes a plurality of light board units 211 arranged in a horizontal strip shape and a front cover plate 212 covering the light board units 211, the light board units 211 and the front cover plate 212 are pressed together on the back plate 10 through the first pressure strip 31 and the second pressure strip 32, and the light board units 211 are pressed between the back plate 10 and the front cover plate 212. Figure 1-3 As shown, the light board layer 20 in this embodiment includes two groups of light board units 211 and a front cover plate 212 , and the display module includes two upper and lower light board layers 20 .

[0031] Specifically, the first pressure strip 31 includes a first connection portion 311 and a first clamping portion 312. The end of the first connection portion 311 is connected to the first clamping portion 312 to form an L-shaped structure in cross section. Preferably, the two are in a vertical connection relationship. The first clamping portion 312 is located on the front of the light board layer 20 away from the back plate 10. The front cover 212 and the light board unit 211 are pressed onto the back plate 10. The first connection portion 311 is in contact with the side of the back plate 10 and extends to the side of the light board layer 20 to limit the up and down displacement of the light board layer 20 in the direction of gravity. The second pressure strip 32 includes a second connection portion 321 and a second clamping portion 322. Figure 3 and Figure 5As shown, the end of the second connecting portion 321 and the middle portion of the second locking portion 322 are connected to form a T-shaped structure. Preferably, the two are in a vertical connection relationship. The second connecting portion 321 also has a plurality of protrusions 323 on the side away from the second locking portion 322, and the back panel has discontinuous adaptation notches corresponding to the protrusions 323. Since the second pressure strips 32 are connected to the middle portion of the back panel, the adaptation notches are manifested as discontinuous openings; the second locking portion 322 of the second pressure strip 32 contacts the front side of the two adjacent lamp board layers 20 away from the back panel 10, and the front cover plate 212 and the lamp board unit 211 of the two adjacent lamp board layers 20 are pressed onto the back panel 10, and the second connecting portion 321 is engaged with the adaptation notch on the back panel 10 through the protrusion 323.

[0032] Specifically, the back plate 10, the light board unit 211, the front cover 212, the first bead 31 and the second bead 32 are all made of colorless transparent materials; preferably, the back plate 10, the front cover 212, the first bead 31 and the second bead 32 are made of high-strength, light-weight and transparent materials such as but not limited to PC (Polycarbonate), PET (Polyethylene Terephthalate) or PMMA (Polymethyl Methacrylate); the substrate of the light board unit 211 is made of but not limited to colorless and transparent glass, and a conductive circuit pattern (not shown) is printed on the substrate and a plurality of lamp beads arranged in a matrix are provided, and the lamp beads are light-emitting semiconductor devices such as but not limited to LED lamp bead packages or LED chips. In order to obtain a better light-emitting effect, a plurality of openings are provided on the front cover 212 in this embodiment at positions corresponding to the LED lamp bead packages or LED chips arranged in a matrix, and the shape of the openings matches the lamp beads to prevent the front cover 212 from reflecting light and affecting the brightness and display effect.

[0033] In this embodiment, several layers of light board layers 20 are clamped on the back plate 10 through the first clamping part 312, the first connecting part 311, the second clamping part 322 and the second connecting part 321 on the first bead 31 and the second bead 32, wherein the first bead 31 and the second bead 32 provide support and displacement restriction for the light board layer 20 in the direction of gravity while clamping the light board layer 20, making the overall structure of the display module more solid; in this embodiment, the above connection method is used to replace the method of bonding each transparent board layer with a glue layer in the prior art, avoiding the negative impact of glue coating on the transparency of the LED transparent display screen, thereby affecting the overall appearance of the display screen. In addition, the connection structure used in this embodiment is simple and convenient for construction, installation and disassembly.

[0034] On the basis of the above structure, in order to solve the problem of the light board layer 20 moving left and right in the horizontal direction, this embodiment adopts but is not limited to at least one of the following two structures to overcome the problem.

[0035] Structure 1: Figure 3 and Figure 6-7 As shown, the left and right sides of the display module in this embodiment are also provided with a plurality of baffles 50 made of transparent material, which extend from the front side of the light board layer 20 away from the back board 10 toward the back board 10, abut against the side of the back board 10 and are connected and fixed by means of but not limited to threaded connection, glue connection, welding or riveting to limit the horizontal movement of the light board unit 211 and the front cover plate 212.

[0036] Structure 2: Figure 4 and Figure 5 As shown, at least one of the first pressure strip 31 and the second pressure strip 32 is provided with a blocking portion 33 at both ends, and the blocking portion 33 extends from the front side of the lamp board layer 20 away from the back board 10 to the back board 10 to limit the left and right displacement of the lamp board layer 20.

[0037] The problem of horizontal movement of the lamp panel layer 20 is solved by adding the blocking bar 50 in the first structure or adding the blocking portion 33 of the first pressure bar 31 or the second pressure bar 32 in the second structure.

[0038] On the basis of the above structure, in order to make the use and installation of the light-emitting semiconductor transparent display module provided by the present invention more convenient and improve the viewing experience, the present embodiment also adopts the following structure.

[0039] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, a support column 40 is installed on the back of the back plate 10 of the display module, that is, on the side of the back plate 10 away from the light board layer 20, and the support column 40 includes a base 41 and a column 42, wherein the base 41 can be made of, but not limited to, a metal material with a high density in order to make the display module more stable, and the column 42 is made of, but not limited to, a high-strength, lightweight transparent material such as PC (Polycarbonate), PET (Polyethylene Terephthalate) or PMMA (Polymethyl Methacrylate) in order not to affect the transparent viewing experience; the back of the back plate 10 and the column 42 are connected by a detachable connection method such as, but not limited to, a threaded connection, and the display module can be stably erected through the connection between the column 42 and the base 41; at the same time, the lower side of the light board layer 20 located at the bottom layer along the gravity direction should have a height difference with the base 41, so that the screen can obtain the effect of floating display of the picture when displaying, so that the user has a better viewing experience.

[0040] Preferably, if Figure 3As shown, the wire circuit pattern on the light board unit 211 in this embodiment is connected to the control device (not shown) of the light-emitting semiconductor transparent display module through the wiring flexible board 213. The wiring flexible board 213 is, for example, a flexible printed circuit (FPC). The back panel 10 has a through hole 12 corresponding to the wiring flexible board 213, and the column 42 has a wire threading groove 421 and a wire. The wiring flexible board 213 passes through the through hole 12 and is connected to the wire in the wire threading groove 421.

[0041] The structure of the column 42 and the base 41 allows the display module to stand upright while ensuring stability, while not affecting the appearance of the transparent display screen. The height difference between the bottom light board layer 20 and the base 41 makes the display screen of the display module feel floating, improving the viewing experience. The wiring structure of the display module is simplified by connecting the wiring board 213 through the perforation 12 to the wire in the threading groove 421 of the column 42, which is convenient for installation and use.

[0042] Preferably, if Figure 3 and Figure 4 As shown, the back panel 10 of the display module also includes a plurality of first frame bars 17 and a second frame bar 18. The plurality of first frame bars 17 are respectively arranged at the upper and lower edges of the back panel 10 on the back side away from the lamp board layer 20, and the plurality of second frame bars 18 are respectively arranged at the left and right edges of the back panel 10 on the back side away from the lamp board layer 20. The first frame bar 17 abuts against the first connecting portion 311 of the first pressure strip 31, and the second frame bar 18 abuts against the blocking bar 50. The abutting method adopts but is not limited to threaded connection, glue connection, welding or riveting.

[0043] In this preferred embodiment, a first frame bar 17 and a second frame bar 18 are provided on the back edge of the back panel 10, which serve as structural reinforcements of the back panel 10 on the one hand, and as abutments with the first pressure strip 31 and the baffle strip 50 on the other hand, thereby reducing the reduction in strength of the connecting structure, helping to avoid damage to the back panel and prolonging the service life of the product.

[0044] Preferably, a plurality of stacked display modules may share the same column 42 .

[0045] When the specification of a single display module is large, if the back plate 10 adopts a whole transparent plate, the size is too large and it is not convenient to transport and install. Therefore, the back plate 10 of this embodiment adopts the following structure.

[0046] Specifically, the back panel 10 may include a plurality of back panels spliced ​​together, such as Figure 8As shown, in this embodiment, the back panel 10 includes a first sub-back panel 15 and a second sub-back panel 16, and the first sub-back panel 15 and the second sub-back panel 16 have a predetermined shape, for example, a T-shaped extension 13 on one side adjacent to the first sub-back panel 15, and the second sub-back panel 16 has a T-shaped slot 14 at a position corresponding to the T-shaped extension 13 and a shape matching the T-shaped extension 13 on one side adjacent to the first sub-back panel 15. The two are spliced ​​together to reduce the maximum specifications of the back panel processing, facilitate transportation, and are tightly spliced; through the mutual connection of the first frame bar 17, the second frame bar 18, the first pressure strip 31, the second pressure strip 32 and the column 42 and other structures, each lamp board layer 20 and the first sub-back panel 15 and the second sub-back panel 16 form a display module as a whole.

[0047] Preferably, since the thickness of the protruding portion 13 is consistent with the thickness of the back plate 10, the depth of the slot 14 is consistent with the thickness of the back plate 10, that is, the slot 14 is a through hole penetrating the back plate 10. In this structure, the protruding portion 13 is easy to pass through the slot 14 during splicing, causing inconvenience in installation. Fig. 9 As shown, the thickness of the protruding portion 13 of the preferred solution of this embodiment is less than the thickness of the back panel 10, the slot 14 is a blind hole with a depth, and the depth matches the thickness of the protruding portion 13. In addition, the edge of the second back panel 16 near the slot 14 and the edge of the first back panel 15 near the protruding portion 13 also have a plurality of matching concave-convex structures 19 to obtain a better splicing effect and solve the problem of inconvenient installation.

[0048] Preferably, if Figure 8 As shown, the back plate 10 has a plurality of hollow structures 11, which, on the one hand, reduce the weight of the back plate 10 and facilitate installation and construction; on the other hand, the hollow structures 11 help the lamp panel unit 211 to have a better heat dissipation effect.
